The mysterious hacker who's giving refunds of (some) of the Ethereum they stole....

File this under 'odd stories in crypto' - a hacker who stole Ethereum valued at over $37 million has given back some of it - twice now. (Worth noting - $37 million is the value of the Ethereum today, at the time it was closer to $7.5 million).

The story behind how he obtained it goes back to July 2017 and the Coindash ICO. The hacker broke into their website, and simply replaced the address for investors to send their ethereum to, to one he controled. People who thought they were participating in the ICO we're actually just sending funds to the hackers wallet.

Then, in September - the hacker returned 10,000 ETH back to CoinCash. Then on Friday he popped up again - returning another 20,000 ETH to CoinDash.

"We have notified the Counter Cyber Terrorist Unit in Israel. The hacker’s Ethereum address will continue to be tracked and monitored for any suspicious activity." CoinDash's CEO Alon Muroch said in a company blog post.

As for the rest of the funds, nothing's been spent - the remaining 13,000 Ethereum is still just sitting in the hackers wallet.
